COUPLING FOR CABLES, WIRES, ROPES, 8w.

Specification of Letters Patent.

Patented Dec. 19, "1911.

Application filed October 28, 1910. Serial No. 589,510

To all whom it may concern:

Be it known that l 'luomas J. Corn, a citizen of the lnited States,residing in the city and C(JHIILV'OIE Philadelphia, State ofPennsylvania,.havc invented a new and useful (louplimg t'or (.lables,Vii-es. Ropes, &e.,

' of which the following is a specification.

My invention consists of a device for coupling or connecting the ends otcables, wires, ropes, etc., so as to form a continuity" of each otherwhether the cables, etc., have been broken or are purposely separated,the incnibers of the device. and the operation thereof being hereinafterdescribed.

For the purpose of explaining my invention, the accompanying drawingillustrates a satisfactory reduction of the same to practice, but theimportant instrumentalities thereof may be varied, and so it is to beunderstood that the invention is not limited to the specific arrangementand organization shown and described.

l igure t represents a top or plan v .w of a coupling, or connection forcables, etc, embodying my invention. Fig. 52 represents a side elevationthereof. Fig. 3 represents an end view there-oh. Fig. 4: represents aplan view of another embodiment;- of my invention. Fig. 5' represents aplan view oi another embcalinmnt of my invention.

Similar letters of retcrence indicate corresponding parts in thefigures.

ilte't'erring to the drawings :-i\ designates a bar or stock preferablyof metal. Rising from a face or side of the same are the heads I B, theportions of which adjacent to said stock are reduced in diameter or ofthe form of inverted cones forming the necks 0. Extending transverselythrough said necks are the passages D, which are open throughout, andadapted to receive the ends of the cables E to be connected. On theterminals of the stock A are the eyes F whose openings are in thelongitudinal direction of the stock, the side walls of said eyes beingcut away forming the throats G, which are on op pesite sides ot'thedevice. On the outer face of the bar or stock intermediate of thethroats G and adjacent the heads I) are the longitudinally extendingchannels G'f The throats G are disposed upwardly and obliquely of thelength of the device and the inlets thereto are preferably below the surface of the necks C.

The operation is as follows: The end portions of the cables to beconnected are directed through the passages I) and then the slack isbent or wound around the necks (l and across the terminals of the cablesand directed toward the eyes F, when the slack is inserted laterallythrough the throats (1 into the interiorofisaid eyes, the cables thushaving a bite on the heads B, and so being held immovably thereon andprevented from slipping, it being evident that the opposite cables areconnected in a tirni and reliable manner. and their continuity is in ameasure preserved. The longitudinal channels G extend beyond the threatsand atl'ord room for the slack to be brought well below the entrance tothe throats G, and when the slackis released the upward and obliquedirections of the throats causes the rope or cable to slip up into saidthroats where it is securely held.

In Fig. l I show a head. with a passage therein, the same being openatits top. or outer endas at. ll so that the cable may be inserted intothe head at said top instead of being passed through the $31110 asyin Fil. In order to stretch and tighten the on Ice I employ separate stocks,each having a head and eye thereon, the end of each stock opposite tothe eye having a longitudinally extending sleeve J thereon, the bore ofthe same being serew-threadcd to receive the screw hi, it being noticedthat a screw is employed for each sleeve, the two screws being securedto or formed with the head L by which they may be turned, it beingnoticed also that the threads of said screws are pitched reversely orright and left, so that when the cables are connected with the stocksand the head L properly rotated, the screws draw the sleeves andconsequently the stocks toward each other, whereby as the cables followthe stocks, they will be stretched and tightened to greater extent as isevident. In order to disconnect the cables, they are withdrawn from thethreats, unwound from the heads B, and removed from the passages I)therein when they are free a is evident.

Attention is especially directed to the fact that when the cables arewound or wrapped around the heads, as the sides flare upwardly, saidcables a re prevented from slipping,- over the heads, this being furtherprevented by the eyes l which serve to hold down the cables as wound orwrapped 0n the heads. Furthermore, it is evident also, that the necks orundercuts C of the heads tiguous, thus firmly clamping the same on andagainst the stock, rendering the non- -slipping or non-giving connectionof the cables with the heads most reliable in its nature. r

i It will be noticed that the stock A has its upper face flat orsubstantially so and the openings or passages D through its conicalmembers C are adjacent to said face. The eyes F are arranged to hold thecable in substantial alinement with. said upper face while the throatsGr serve to raise the cables when a pull is exerted on the latter.

Having thus described my invention what I claiin'as new and desire tosecure by Letters Patent, is As an improved article of manufacture, acoupling device comprising a stock having a flat upper face and at anend thereof an eye extending in the longitudinal direction thereof aconical head rising from the upper face of said stock and provided witha transverse opening through said conical member adjacent said face,said stock being formed with a channel leading from said opening to theouter end of the eye and with an upwardly and obliquely disposed throatcommunicating with said channel and extending into said eye, said eyebeing arranged to hold the cable in substantial alinement with saidupper face and said channel affording access to the throat andfacilitating the introduction of a cable thereinto, and the throatserving to raise the cable when a pull is exerted onthe latter.
